pltcfg file Default Printer Name

I'm trying to set the default printer name in a cutomized printer.pltcfg
file so it does not match the windows default printer. It works fine for
a locally installed printer but when I try to set the name to a share connected
printer on my machine it fails. I've tried using the printer name shown in
my control panel settings and the UNC path to the share.

Is there a way to set this to a network printer?
